To conserve registers when using VDEW devices, you
should set all unused registers to “Not Used” and
place them at the end of the list. The DTU3005 will
only allocate registers for those containing device
data. (This does not apply to SEAbus devices, for
which the DTU3005 allocates 16 registers regardless if
they are used or not.)

Device Text Setup (7SJ600 Only)
The Device Text to Values Table menu item is only
available for configuring the 7SJ600 relay. It is used to
convert status codes returned from select parameters
in the 7SJ600 relay (only) to values in a format useful
to the system connected to port 2 of the DTU3005.
This affects the status readouts from the device's
binary inputs, signal and trip rated contacts, and the
LEDs.
To edit this table, select
Device Text to Values Table
from the
Edit
menu. This selection is only available
when the device protocol for port 2 is set for “VDEW.”
Once open, 64 conversions can be defined. To define
a conversion, enter the 7SJ600 relay status code in the
Text #
column and enter the corresponding output
value desired in the
Value
column.
